Problems-
1. Suppose the marginal product of the 23rd worker is eight boxes of output. Average product when 23 workers are employed is five boxes per worker. We can conclude that:
A) average product is neither rising nor falling.
B) marginal product is neither rising nor falling.
C) marginal product is falling.
D) average product is rising.
2. Use the following to answer the question:
Workers Output MP AP
1 5 5 5
2 12 7 6
3 21 7 -
4 31 10 7.75
5 40 9 8
6 48 8 -
7 6 7.71 -
8 58 3 7.13
9 60 0 6.33
10 60 -3 5.4
Referring to the table and figure above, adding a fifth worker leads to:
A) diminishing marginal returns.
B) constant marginal returns.
C) negative marginal returns.
D) increasing marginal returns.
Additional Information-
These multiple choice problems belong to Economics. The first problemis about calculation of marginal product and the second problemis about calculation of marginal returns.
